The modulo operator determines the integer remainder of the division. This operator is not ANSI SQL supported, however, most databases support it. The following are some more useful mathematical functions to be aware of since you might need them. These functions are not standard in the ANSI SQL-92 specs, therefore they may or may not be available on the specific RDBMS that you are using. However, they were available on several major database systems that I tested. They WILL work on this tutorial.
